CAN-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 424,394, dated March 25, 1890.

Application filed March 30, 1889- Serial No. 305,350. (No model.)

To all whom it may concern.-

Be it known that I, EMIL WILDI, of Highland, in the county of Madison and State of Illinois, have invented a certain new and useful Improvement in Gan-Filling Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,for1ning part of this specification, and in which Figure I is a side elevation of myimproved machine. Fig. II isa top view. Fig. III is a view of the slotted top of the frame. Fig. IV is a transverse section of the small cylinder, taken on line IV IV, Fig. V. Fig. Vis alongitudinal section of the small cylinder, taken on line V V, Fig. IV, and showing the piston in elevation. Fig. VI is a view illustrating the clamp for tightening the joint in the pipe between the tank and the large cylinder. Fig. VII is a transverse section taken on line VII VII, Fig. II. Fig. VIII is a longitudinal section of the large cylinder, taken on line VIII VIII, Fig. II, and showing the piston and its stem in elevation. Fig. IX is a vertical section of the filling-nozzle, taken on line IX IX, Fig. VIII. Fig. X is a transverse section through the stem or red of the main-cylinder piston, taken on line X X, Fig. VIII. Figs. XI and XII are sections through the main valve, taken on line XI XII, Fig. VII. Figs. XIII and XIV are transverse sections through the main valve, showing the lugs or ears and the stop-pin that limit the movement of the main valve, these sections being taken 011 line XIII XIV, Fig. VII. Figs. XI and XIII illustrate the parts in the position they occupy when the main valve is open, and Figs. XII and XIV in the position they occupy when the main valve is closed.

My invention relates to an improved machine for filling cans with liquidsas, for instance, such liquids as milk, mineral and other waters, paints, &c.; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, 1 represents the base or bed plate, to which are secured posts or standards 2, connected at top by a plate 3.

4 represents part of a tankcontaining the liquid to be filled into the cans.

5 represents a cylinder, properly supported by the bed-plate, and which communicates with the tank 4 by means of a pipe 6. (See Fig. VII.) In the pipe 0 is located a main valve '7. This is shown clearly in Figs. VII, XI, and XII. On the upper end of the main valve 7 is a head or disk 8, from which de pends a pin 9, which limits the movement of the main valve by coming against projections or ears 1O onthe casing or housing 11 of the main valve. This feature is illustrated in Figs. XIII and XIV. The pin and lugs or cars permit the main valve to move far enough to entirely close or open,but prevent it moving too far in either direction. The pipe 6 is made in two parts, one telescoping the other, as shown in Fig. VII. The outside portion of the pipe is slotted at 6%,- and has a clamp 6., (see Figs. VI, VII, XI, and XII,) to secure a tight joint, while allowing the parts to be disconnected for cleaning purposes. The clamp has an extension 6 by which it is secured to one of the posts 2 by aset-screw 6, for the pun pose of assisting in supporting the cylinder 5.

Projecting upward from the head or disk 8 are anumber or series of pins 12. (See Figs. II and VII.) These pins are engaged by teeth or projections 13 on a plate 14, and it will be seen that as the plate 14 is moved from the position shown in full lines, Figs. I and II, to the position shown in dotted lines, same figures, the disk 8 (and consequently the main valve 7) will be turned from the position shown in full lines, Fig. II, to the position shown in dotted lines, same figure; or, in other words, the main valve will be moved from its open to its closed position.

My preferred manner of operating the plate 14 consists of a cord or cable 15, which passes from a suitable lever or treadle (not shown) over a pulley 16 to a pin 17, which passes up through a slot 18 in the top plate 3, and is made fast to a projection 19, depending from the under side of the plate 14. This is illustrated in Fig. I. The plate 14 moves on the upper ends of lugs 20, projecting upward from the top plate 3, and the plate is held from vertical movement by a rod 21, on which it slides, and which passes through the lugs 20, and also through the .lug- 19 and another lug 22 on the plate 1 1. It will thus be seen that by pulling on the cord or cable 15 the plate 14. will be moved from the position shown in full lines, Figs. I and II, toward and to the position shown in dotted lines, same figures. Then, when the pressure is removed from the cord or cable 15, the plate 14 is moved back again to its normal position by means of a spring 23, connected at one end to a pin 24, projecting upward from the top plate 3, and connected at its other end to a projection 24 on the plate 14. This latter connection is made by means of a threaded pin or rod 25, on which is a thumb-nut 26, and by tightening or loosening on this nut the tension of the spring 23 may be regulated, as desired.

27 represents a nozzle in the lower part of the cylinder 5, at the inner end thereof. (See Figs. I, VII, and VIII.) For the construction of this nozzle, see Fig. IX. It consists of an outer shell 28 and an inner shell 29, between which is an annular chamber 30. The cans to be filled are placed beneath this nozzle, as shown by dotted lines at 31, Fig. I. This nozzle 27 forms the bottom of a dischargeport 32 in the cylinder 5. The dischargeport 32 is controlled by a discharge-valve 33. The discharge-valve is provided with a stem or rod 34, extending up through a stuffingbox 35 in the top of the cylinder, (see Fig. V111,) and connected at its upper end to a cross head or piece 36. (See Fig. I.) The rod or stem 34 passes through a head 37 on an arm 38, secured to the cylinder 5 and provided with an extension 39, through which passes a rod 40, extending upward from the bed-plate and held to the extension 39 by a set-screw 41. To the head 37 is pivoted, at 42, a lever 43, the outer end of which is adjustably connected by means of a pin and holes 44 to the upper end of a rod 45, which may be operated by the same lever or treadle as that employed for moving the cord or cable 15. The parts should be so disposed that the cable will be operated to move the plate 14, as described, before the rod 45 commences to move. WVhen the lever 43 is operated, its inner end impinges against a friction-roller 46, secured to the cross-head 36.- By this arrangement the discharge-valve 33 is raised from the position shown in full lines, Fig. VIII, to the position shown in dotted lines, same figure, to allow the liquid to pass from the cylinder to the can. WVhen pressure has been removed from the rod 45, the dischargevalve 33is closed by the action of a spring 47, surrounding the stem or rod 34, between the head 37 and a collar or projection 48 011 the rod 34.

The extension 39 of the arm 38 and the rod 40 serve to assist in supporting the cylinder 5, and the rod is held from movement on the bed-plate by a hook 49, pivoted to the bedplate at 50, and which is capable of being swung around into engagement with the rod.

By this manner of supporting the cylinder it will be seen that it can easily be handled for cleaning purposes.

51 represents a piston located within the cylinder 5 and provided with a stem 52, extending through a neck 52% on one of the heads of the cylinder. The stem has on its outer end a button or disk 53. (See Fig. VIII.) The neck is slitted at 54, (see Fig. I,) and over it fits a clamp 55, by loosening which the piston may be moved in or out, and then by tightening the clamp held to its adjustment, for the purpose hereinafter mentioned. The form of the clamp is illustrated in Figs. I, II, and X.

56 represents a tube or pipe extending upward from and communicating with thetop of the cylinder 5. (See Figs. I and VIII.) On the upper end of this pipe is seated an airvalve 57, having a stem 58, over the upper end of which fits an arm 59, supported by a post 60, secured by an arm 61 to the pipe 56 beneath the air-valve 57. This air-valve has a marginal flange 62, against which the end 36% of the cross-head 36 impinges when raised by the lever 43 (as the latter reaches the limit of its movement) to open the air-valve by moving it from the position shown in full lines to the position shown in dotted lines, Fig. I. WVhen the lever moves back to its normal position, the air-valve is closed by a spring 63, surrounding the stem 58, between the air-valve and the arm 59, through which the stem passes freely.

64 represents a pipe or hose connected to the pipe 56, which is provided with a sight tube (55 to indicate when the cylinder 5 is full. The outer end of this pipe or hose may be placed in a can or receptacle (not shown) to catch theover drip or run.

66 represents a small cylinder, which may be secured to one of the posts 2, as shown at 67, Fig. V.

68 represents a pipe or hose forming a communication between the cylinder 66 and the chamber 30 of the nozzle 27. (See Figs. I, IV, and VIII.)

69 represents a check-valve located in the pipe or hose 68. (See Fig. IV.)

The cylinder 66 has a piston 70, the stem or rod 71 of which is connected at 72 to one end of a lever 73, pivoted at 74 to the bedplate 1. The piston is moved outward in the cylinder by a spring 75 bearing against the bed-plate and against a pin 76 011 the lever. The piston is moved inward by a roller 77 on the plate 14, which comes against the upturned end 78 of the lever as the plate 14 moves toward the position shown in dotted lines, as described. The upper end of the lever has an inclined extension 79, against which the roller 77 bears to depress the lever and operate the piston.

80 represents a pipe or hose connected to the bottom of the cylinder 66, and which is provided with a check-valve 81. (See Figs. III, IV, and V.) This pipe or hose may discharge into a can or other receptacle.

The operation is as follows: The parts be- IIO ing in the position shown in Figs; I and VII, the liquid runs from the tank 4 into the cylj The filling of the cylinder is indicated by the" inder 5 until the latter becomes filled.

glass tube 65. Power is then applied to the cable 15, which, as described, operates the plate 14, and through it turns the main valve 7, as mentioned, and shuts off the supply from the tank 4. The rod 45 and the lever 43 are then operated, and the discharge-valve 33 is thus opened, when the liquid will pass from the cylinder 5 into the can. As the liquid passes from the cylinder, it is of course necessary to admit air to prevent a vacuum, and this is accomplished by the cross-head 36 coming against the air-valve 57 and opening it. The amount of liquid contained in the cylinder is just enough to fill the can, and this amount may be varied at will by changing the size of the cylinder back of the piston 51. This is done by moving the piston in or out and securing its adjustment by the clamp 55. The latter part of this movement of the plate 14 forces the piston of the small cylinder 66 inward, as mentioned. As soon as the liquid has run from the cylinder into the can, pressure is removed from the cable 15 and rod 45, when the parts will all return to their former position, and the piston 70 of the cylinder 66 will be forced out ward again by the action of the spring 75, the lever '78 moving from the position shown in dotted lines, Fi .1, to the position shown in full lines, same figure. This movement of the piston causes avacuum in the pipe 68, the result of which is to suck or draw any liquid that may be left on the nozzle 27 through the pipe into the cylinder, from where it passes through the pipe into any suitable receptacle. By providing the arrangement for sucking or drawing the surplus liquid from the nozzle the cans or vessels can be removed the instant they are filled without being smeared by dripping from the nozzle, and in case of valuable liquids being handled there is no loss accruing from waste.

It will thus be understood that the operation of the machine is continuous and entirely automatic, and by having the parts arranged as I have described them they may be quickly and easily removed for cleansing purposes.
